RAR archive associating the STI IS1462 machine with the FIC LM10W board at revision 0.7. STI is a brand that sold systems built on ODM designs, and FIC, First International Computer, supplied this motherboard. The contents are not named, though collections like this usually provide schematic pages to open as PDF after extraction. Use them to follow power rails, find test points and diagnose shorts, and check that the PCB carries the LM10W code and 0.7 revision before trusting values.
